| DTC Strategy |
Case 1 |
- ECM internal inspection (knock sensor recognition faulty)
|
- Poor connector connection
- ECM
- Irregularity battery
|
| Case 2 |
- ECM internal inspection (barometric pressure sensor faulty)
|
| Case 3 |
- ECM internal inspection (internal ATIC communication faulty)
|
| Case 4 |
- ECM internal inspection (EWGA overheat)
|
| Enable Conditions |
Case 1 |
- Ignition "ON"
- Engine speed is higher than 32 RPM
|
| Case 2, 3, 4 |
|
| Threshold Value |
Case 1 |
- Abnormality detected during the determination of knock sensor signal (internal ECU diagnosis) plausibility
|
| Case 2 |
- Abnormality is detected during ECU self-diagnosis (H/W circuit, sensor memory)
|
| Case 3 |
- ATIC communication error (internal ECU diagnosis) is detected
|
| Case 4 |
- When the temperature of 200°C or higher is measured during ECU power diagnosis
